I have a belly button hernia and it is getting worse. The doctor told me to avoid getting surgery on it until it gets in the way to the point where I have to have surgery since the surgery will hurt and keep me from working out for awhile.
He said 3 to 6 weeks depending on the severity of it.
Not really sure how great he was, but I still have the hernia and it doesn't bother me all of the time - but it is getting worse - not really sure (other than pain) of what to look for in terms of "okay, now is time for surgery"
